There must be a stop loss management for every trades we make. We must not let our funds lose because of lack of risk management. Maybe, if you can win most of your trades without stop loss then you can do it. But for me, we must have stop loss since we don't know where our trades going on. There are times that our plans move in different ways and if you are unlucky, your loss will goes high if you let your funds burn in market. It take years when you see your money coming back again.
